OASMNR & SASBA (Overt Aggression Scale Modified for NeuroRehab & St. Andrew's Sexualised Behaviour Scale)
These assessments are observational tools used to record and measure detailed aggressive behaviours (SASBA focusses on sexualised aggression) in patients with brain injuries. This allows teams to understand whether changes to care are effective by comprehensively measuring changes in behaviour.
Open a new OASMNR / SASBA form by opening the side navigation bar and clicking “+OASMNR” or “+SASBA”
Choose a patient
Choose the time of behaviour (default is time that the form was opened)
Choose a type of behaviour (if two different behaviour types occurred simultaneously then choose the most severe)
Choose a behaviour severity
Choose the number of occurences by clicking the +/- buttons or typing a number directly in
Optionally add a description of what happened
Choose any optional contributing factors
Choose an antecedent (the last thing observed by staff before the behaviour occurred). If no options match your observation then choose “Other” and enter something new.
Choose an intervention (the last action taken by staff before the behaviour ended). If no options match your observation then choose “Other” and enter something new.
Turn on the Create more switch to open a fresh form for the same patient immediately after submitting one (this can be useful during live observation of continuous behaviours)
Click “Submit”
2. Analysing the data
Behaviour over time chart
Severity (weighted, mean) line
The four available behaviours for each assessment type are scored 1 to 4 in the order displayed (VA, PO, PS, PP for OASMNR, and VC, NC, E, TO for SASBA).
The four available severities (1, 2, 3, and 4) are scored as named.
Each single submission creates a “weighted” severity by multiplying these two values together between (coming out at between 1 and 16).
Each point on this line is the mean average from that time-slot on the graph; it adds all weighted-severities together and divides by the combines number of “occurences” (aka “frequency”). How Melo equates severity levels between assessment types
Frequency line
Shows how many submissions were recorded in each period
Intervention intrusiveness line
Shows the mean average instrusiveness value for all submissions in each period based on the following assignments to the interventions:
Aggression ignored — score 1
Closer observation — score 2
Talking to the patient — score 3
Special programme — score 4
Physical distraction — score 5
Isolation without seclusion — score 6
Holding patient — score 7
Immediate medication given by mouth — score 8
Seclusion — score 9
Use of other restraints — score 10
Immediate medication given by injection — score 11

Allows you to annotate timestamps on the graph. This can be useful to highlight how changes in care affect the behavioural lines.
